JAMES A. DONALDSON, OF GREENVILLE, PENNSYLVANIA.

METAL-WORKING TOOL FOR TURNING AXLES.

SPECIFICATION forming part of Letters Patent No. 536,609, dated April 2, 1895.

Application filed May 4, 18 94. Serial No, 510,053. (No model.)

To all whom it may concern:

Be it known that 1, JAMES A. DONALDSON, a citizen of the United States, residing at Greenville, in the county of Mercer and State of Pennsylvania, have invented certain new and useful Improvements in Metal-Working Tools; and I do hereby declare the following to be a full, clear, and exact description of the mvention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in metal working tools, and particularly to that class of tools used for turning and trimming vehicle axles.

Primarily the object of my invention is to provide a simple, compact and effective device which may be readily applied to the Work or material to be operated upon.

A-further object of the invention is to provide a simple and efiective centering device for properly adjusting the work within the cutter head or plate.

With these objects in view the invention consists in the construction and arrangement of the parts as will be more fully hereinafter set forth and then defined in the claims at the end of the description.

Referring to the accompanying drawings, forming a part of this specification, Figure 1 is a front elevation of the invention. Fig. 2 is a side elevation. Fig. 3 is a vertical sectional view on the line IIIIII of Fig. 1, with the centering device in position for adjusting the work. Fig. 4 is a vertical section on the line IVIV of Fig. 3; and Fig. 5 is an elevation of the hand nut.

In the drawings A may designate a vehicle axle in position for having a shoulder turned or cut thereon, though'it is obvious that the invention would be equally applicable for cutting pipes, bars and other articles. Surrounding the axle is a hollow casing or tube B having at or near one end thereof an en-v larged annular portion or band 1) preferably formed integrally therewith; the said casing being provided with an annular groove 1) on the exterior thereof and adjacent to the band I). Radially arranged and passing through threaded apertures of the casing is a series of screw-threaded bolts b and 1) preferably located respectively near the fore and rear part of the casing. These bolts are suificient in number to adjust and retain the work within the casing B. Slidingly held upon the casing is a sleeve 0 having an annular shoulder 0 at one end, and its opposite end provided with an exterior screw-thread c. This sleeve is provided with slots or slotted apertures c for the passage of the bolts b which bolts prevent rotation of the sleeve but allow same to slide or move lengthwise of the casing 13. Engaging the screw-threaded end of the sleeve is an interiorly threaded hand nut D, which is rotatably held upon the casing B by means of the shoulder 61 engaging the annular groove 1) of said casing; the said groove and shoulder permitting the nut to rotate but preventing any lengthwise movement of said nut. The nut is preferably composed of two interlocking members 01 and 01 securely bolted together, each member being provided with suitable handles d for turning the nut 'to move the sleeve 0 back and forth.

E is a tool-carrying head or plate rotatably held upon the sleeve 0 between the shoulder a and a collar 0 the said collar having an interior screw-thread engaging, the screw-thread of the sleeve and adj ustably held thereon by a set-screw c for the purpose of taking up any lost motion that may occur by the wearing of the cutter head, and to prevent any lengthwise movement of said head.

The plate or head E has arranged upon the face thereof the jaws e arranged to slide in dove-tailed grooves in said plate. These jaws are adapted to hold the different kinds of cutting tools used in such work; the said tools being retained in the jaws by set screws or in any other suitable manner. The adjustment of the jaws e is secured by the hand screws or bolts e. These screws pass through-threaded apertures in the brackets or bosses e and engage, with their lower ends, the jaws e in such manner as to rotate in same, but to raise or lower said' jaws by the engagement'of the threads of the screws with the threaded ap ertures of the brackets. The brackets or bosses 6 may be secured to 'or formed iute grally with the cutter head'or plate, as desired.

To properly center the work within the easing I provide a separate centering device F, as shown in Fig. 3. This device has a cupshaped bushing f adapted to snugly tit the bore of the casing B, and an outwardly extending screw-threaded stem or bolt f preferably formed integrally with said bushing. Arranged in the end of the bushing are the centering jaws f preferably four in number, though more or less may be used if so desired. These jaws are pivotally secured to the bushing and have their inner ends arranged to clamp and adjust the work, while the outer ends have cam faces f adapted to be acted upon by the tapering plug or out f. The plug f is provided with an internal screwthread f which engages the screw-thread of the bolt or stem f; the said plug being turned by hand or provided with a polygonal surface so that a wrench may be used.

To turn or cut the Work, it is first necessary to center the same by the device F, as shown .20 in Fig. 3, by turning the plugf which acts upon the centering jaws f The work is then secured by the bolts 11 and b and the proper tool brought in contact with said work by the screw 6 operating the jaws e. By revolving the cutter head or plate by hand the tool will out according to the degree the same is forced into the work. This cutting may be continued by forcing the tool again into the work and revolving the head, or the work may be 0 turned lengthwise by simply turning the nut D, which will cause the sleeve 0 and head E to move, and by revolving the head E as it moves with the sleeve.

I have shown two cutters, arranged on the 5 head, but I may increase this number or simply use one if so desired. Instead of using the cutters I might place a solid die in the jaws and thereby adapt the machine for cut ting threads. Some of the parts which are integral with otherparts may, in some instances, be made removable. Instead of the plug of the centering device being made with an internal thread the bore of same may be perfectly smooth and adapted to slide upon the Stem of the bushing.

Other changes of substantially like charracter to my invention may be made without departing from the spirit of the invention.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A tool of the character described comprising a tubular casing, retaining devices arranged in said casing, a sleeve slidingly held upon the casing, a tool carrying head arranged to rotate upon the sleeve, together with means for adjusting the cutter in the head, substantially as described.
